Title:
FUEL PROPERTY DETERMINATION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2011/101962
Kind Code:
A1
Abstract:
Disclosed is an internal combustion engine fuel property determination device which can determine the properties of components included in fuel. The disclosed internal combustion engine fuel property determination device is provided with: a relative dielectric constant detection means which detects, as a dielectric constant parameter, either the dielectric constant of the fuel, or the physical quantity correlating with the same; a fuel temperature detection means which detects the temperature of the fuel; and a fuel property determination means which acquires dielectric constant parameter detection values at a plurality of points having different fuel temperatures, and determines the properties of components included in the fuel on the basis of the dielectric constant parameter detection value and the fuel temperature at each point. The fuel property determination means determines which of the components from among the plurality of components having different dielectric constant temperature dependency properties are included in the fuel.
